My Italy:Design and usability evaluation of an M-Tourism prototype


Published on

Short paper presente @Enter2010 in Lugano
In this paper we describe the prototype of a location-based M-tourism application called My Italy, developed by the Usability and Accessibility Laboratory (LUA) University of Rome Sapienza. My Italy is a mobile multimedia tourist guide capable of supplying the mobile user with context-aware information during travel in a fast and easy way.

Main Characteristics of MyItaly<br />The main characteristics of the system are:<br />GPS localization<br />Updated information through the wireless network<br />Multimedia Presentation (SMIL) <br />Guided Tours vs. Serendipity<br />Modular Information Architecture<br />ENTER 2010 RESEARCH TRACK<br />7<br />Objective = Simplicity + Rich User Experience <br />
  11. 11. Challenges: Displaying Info<br />Provide fast and correct info <br />Avoid cognitive overload<br />Capture user’s attention<br />ENTER 2010 RESEARCH TRACK<br />8<br />Map and Icons: images allow access to information at a glance. Map zooming is related to POIs density.<br />Text Alternative: makes searching for information easier.<br />Multimedia presentations: present some brief facts in a far more engaging way, showing perspective and details that are not normally visible by the user.<br />Information Architecture: different levels of content helps to avoid cognitive overload.<br />
  12. 12. Challenges: Navigation<br />less time to plan -&gt; need to plan on the go <br />need to harvest time -&gt; pre-planned tour<br />freedom to choose -&gt; serendipity<br />ENTER 2010 RESEARCH TRACK<br />9<br />Guided vs. Random discovery<br />Nearby suggestions : the application will communicate the proximity of POIs, routes and potentially interesting events for tourists through a vibration of the device. In this way the application meets the typical discovery needs of a journey. <br />Guided tours : pre-planned itineraries organized in categories. Set info is available at a glance: the distance from the starting point, the length and duration of the itinerary. Multimedia presentations are also available.<br />

The UI: Guided Tours<br />ENTER 2010 RESEARCH TRACK<br />13<br />Step 1:<br />A list of the closest “Guided Tours” available is shown. <br />The “others itineraries” button extends the seeking range.<br />Step 2:<br />An overview of the tour and a few options:<br /><ul><li> starting the tour,
  21. 21. seeing an audiovisual presentation ,
  22. 22. displaying the route to follow.</li></ul>Step 3:<br />A brief textual description and a few options:<br /><ul><li> extended description,

  28. 28. Results & MainIssues<br />All users completed the tasks.<br />80% of users find MyItaly easy and fun to use .<br />Weaknesses:<br />Map: problems getting oriented, latency during rapid movements ,and fast user interaction (i.e. Scrolling) .<br />Absence of social – personalized functions.<br />Strengths:<br />Multimedia presentations: even if interrupted, users tend to remember multimedia presentations better than textual ones.<br />Modular Information Architecture: ease of finding information.<br />ENTER 2010 RESEARCH TRACK<br />18<br />Results:<br />
